WELL-FLowING DEVI-or.

Specicaton of Letters Patent.

Patented Deo. 19, 1916.

Application filed August 10, 1915. Serial No. 44,796.

T all lwhom t may concern:

' the following is a specification, reference being had therein tothe accompanying drawing.

My invention relates to improvements in well flowing devices, the primary object of which is to devise a mechanism which will operate upon a minimum amount of pressure. l o l Another object of my present invention is to devise a mechanism of the character described which will operate with a predetermined quantity of pressure and flow the liquida predetermined height while the pressure remains consta-nt.`

A still further object of the present improvement is to devise such a mechanism of simple construction and having but few movable parts. v f

Other objects'and advantages of the preslent improvement will be set forth in the following description and drawing inwhich'- Figure 1 is a sectional view of a well casing with my improved iowing mechanism placed therein. Fig. 2 is an enlarged sectional view of one of the ejector nozzles. Fig. 3`is a cross-sectional view taken on the l line 3 3 of Fig. 2.

Referring now to the drawings in detail in which like reference numerals designate similar parts, 1 representsv the well casing which is of the usual type. Within the saidl casing I provide a plurality of sections of tubing, indicated by the numeral2, having their ends externally screw-threaded at 3.

These sections of tubing may be of any desired length, depending upon how far apart the ejector nozzles are placed, as will be hereinafter described.

Screw-threaded upon the lower end -of each of the sections of tubing 2, is a cap 4, having internal screw-threads 5, meshing with the screw-threads 3 on the tubing 2. The lower end of the cap 4 is provided with internal screw-threads 6, meshing with eX- ternal screw-threads 7 carried' upon the upper end of an ejector casing 8. The lower end of the casing 8 is provided withy an opening 9, which is internally screw-threaded at l0, which screw-threads meshvwith the internal screw-threads 3, carried by the upper end of the next sectionof tubing 2, eX-

tending downwardly below it. The ejector casing 8 is hollow and has an enlarged interior opening 10 which is of greater diameter than the opening 9, and also of greater diameter than the sections of tubing 2. The difference in diameter of the two openings forms shoulders 12 at the -upper and lower ends of the casing and serving as stops for the piston hereinafter to be described.

Mounted within the opening 10 is a recipro-` cating piston 13, the upper end of which is` formed into a conical nozzle 14 having a reduced opening 15. The piston is of a length lessthan the length of the enlarged opening 10 of the casing 8, whereby a region of reciprocationl is left. The lower end of the piston 13 is provided with a web 16 placed a distance above the lower end of the heater forming a cup 17, the object of which will be hereinafter set forth. One "wall of the cup 17 is provided with a plurality of openings 18, which are adapted to communicate with a plurality of passages 19 when the piston is in its uppermost position, the object of which will be hereinafter set forth. Above the web 16 on the opposite side of the piston is an opening 20 which is adapted to communicate with .a passage 21 formed through the adjacent side .of the ejector cassections of tubing-2 is placed -within the well-casing, the-lower end of the lowermost section of tubing submerged in the' oil or water in the bottom of the well. Air-pressure Pis then fed into the casing at a point outside of the sections of tubing 2 and the ejector casings 8. This air or gas may be of any desired pressure according to the force with/which it is desired to eject the liquid from the well. However, the pressure must be sutlicient to cause the water to flow up withinthe lowermost section of the tubing 2 and exerting its pressure against the cup 17 of the piston 13, force the said municating with the well-casing, the said piston upward to the limit of its upward movement'. After the piston has moved a very short distance under the action of the pressure, .it will throw the openings 18 into communication with the plurality of' passages 19whereby4 the water will be bypassed through the opening 18 and the said passages 19 and thence upwardly into the section of tubing 2 above the piston. The water will be passing through the by-passes 19 while the piston is moving upwardly and until the said piston closes the by-passes 19. As thepiston 13 moves upwardly, it will register the opening 20 in the piston and the passage 21 in the ejector casing 8, there- ,by admitting air .under pressure from the well casing which will act on the by-passed waterl passed above the piston and expel it under extenuated pressure through the ejector nozzle openings 15. It is to be un- `derstood that the waterfafter lifting the piston and by-passing water through the passages 19, becomes reduced in pressure and is not sullicient to hold the piston 13 upwardly and consequently the fsaid piston will drop. The dropping of the piston 13 will close the by-passes and the pressure will then be sufficient to again raise the piston and by-pass another charge of water to the section "of tubing above it. The air expelled from the nozzle opening 15 will mingle with the water by-passed through the passages 19 and force the said water upward under pressure sufficient to operate the next piston above it.- This operation is continued, each piston operating as the water-supply reaches it. Since the lair supplied within the casing is constant the flow of water andair and reciprocation of the pistons will be constant so that the water and gas will be expelled from the upper end of the uppermost tubing in a continuous stream.

Having thus described my invention,
